DIAL TELEPHONE PAY STATION Filed 'July 13, 1936 Patented Jan. 12, 1937 DIAL TELEPHONE PAY STATION George A. Long, Hartford, Conn, assignor to The Gray Telephone Pay Station Company, Hart- 10 Claims.

My invention relates to that class of telephone apparatus which are automatic in character and which, are provided with means for collecting pay for the use of the apparatus, and an object of my invention, among others, is the production of a dial mounting for such apparatus which mounting shall be comparatively light in structure and particularly secure so far as unauthorized access to the money compartment is concerned.

A portion of a telephone apparatus embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained is illustrated in the accompanying drawing in which Figure 1 is a front view of the upper part of the case of an automatic pay station telephone embodying my invention.

Figure 2 is a side view of the same.

Figure 3 is a front view on enlarged scale of the dial and its mounting with parts broken away to show construction.

Figure 4 is a view in section on a plane denoted by the dotted line i-fi of Fig. 3.

In the accompanying drawing the numeral 5 denotes the upper part of the instrument case of an automatic telephone pay station which is of ordinary construction and which is secured to a back plate 55, said case being provided with a coin plate I in a manner common to structures of this class.

A dial case or receptacle 8 is secured to the front face of the instrument case 5 near the upper part thereof this case embodying the principal features of my invention. It is of generally ringlike shape embodying an indicia ring support 9 which is round when viewed from the front, this terminating at the back in a calling case support it which is adapted to be secured squarely against the front face of the case 5, and as shown in Figs. 2 and 4 of the drawing.

The support 9 has a lip l i extending around its periphery at the front thereof and surrounding a seat l2 for an indicia ring it. This ring has locating posts Hi projecting inwardly from the back face thereof, these posts preferably, and as shown herein, being three in number located at different distances apart to compel the plate to be placed in a certain position when secured. The ring l3 bears characters 15 arranged in a. manner common to structures of this type and it is essen tial that when secured in place this ring shall be always in the position shown and have proper relation with respect to a finger stop E6 to be more particularly hereinafter described. Lugs IT project radially inward from the ring or support 9, these lugs being bored at 18 and counterbored at l9, the posts l4 projecting into the counter-bored portions and screws 20 projecting from the rear of the lugs through the holes i8 and into the posts [4, and as shown in Fig. 4 of the drawing. It will be noted that these screws 20 are covered by the front face of the instrument case 5 so that access cannot be had to them and the indicia ring !3 cannot therefore be removed without removing the entire structure from the front of the case 5.

Ears 2! project from the back or lower part of the lugs H and an ear 22 projects inwardly from the inner wall of the support In, there being two N of the ears 2| and one ear 22 evenly spaced apart and forming seats for a calling case 23 which is secured in place within thesupports 9l0, said calling case also being seated upon a ledge 24 projecting from the lug I! located at the upper part of the structure, and as shown in Fig. 3 of the drawing. A chamber 25 is formed in the front face of the case 5 and calling mechanism secured to the back face of the case 23 is located in this chamber. Screws 26 project through the back Wall of the chamber 25 into the calling case 23, these screws passing through holes formed through the ears 2i-22, as shown in Figure 3 of the drawing.

Lugs 2l28 project inwardly from the inner wall of the calling case support ID, the lug 21 being located at the bottom of the structure and the lugs 28 being of similar formation located opposite one another nearthe upper part of the device. Screws 29 extend through the front wall of the case 5 into threaded openings in said lugs 2l28, as shown in Figures 3 and 4 of the drawing, for the purpose of securing the structure as a whole in place on the face of the case 5.

From this it will be seen that the dial mounting as a whole is secured in place and can only be removed by access from within the case 5, the calling case 23 being secured in a similar manner and access to the screws 20 that secure the ring i3 can be had only by removal of the entire mounting from the front of the case.

The ring I3 has a notch 30 through which the finger stop- I B hereinbefore referred toextends, and as shown in Fig. 1 of the drawing, this serving to properly position the calling case 23 to receive the screws 26. A finger dial 3| is rotatably mounted on the front of the calling case and underlying the finger stop It in a manner common to telephone apparatus.
